N11 is a three-digit shortcut to reach special community services. The numbers are set aside by the Federal Communications Commission (FCC) and operated by the provider of the service. 311 - Non-emergency police, fire and municipal business. Local and municipal governments will administer 311 calls. 711 - Telecommunications Relay Service (TRS) for the speech and hearing impaired. The Federal Communications Commission (FCC) in CC Docket 92-105, specified how 211, 311, 511, 711 and 811 codes would be used for various types of public information. In order for 988 to work, the FCC required Washington state to implement 10-digit dialing for its Eastern Washington area code 509 starting in 2021. The entire state of Washington is now operating under mandatory 10-digit dialing, even when making local calls.
